Small habits, earlier warnings
You cannot see inside a slab or wall, but you can notice change. A meter that was still last month and moves this month, a toilet that has started refilling on its own, a sprinkler valve box that now holds water: each is an early signal. A routine turns those signals into action before a ceiling stains or a floor lifts.
None of these checks takes more than a few minutes. Pair them with something you already do, such as paying the water bill or changing a smoke alarm battery.
Monthly checks
| Check | How | What you are looking for |
|---|---|---|
| Meter test | Everything off, watch the low-flow indicator for 10 minutes | Any movement |
| Bill review | Compare usage units with last month and last year | Unexplained increases |
| Quick walk-through | Under sinks, around toilets, near the water heater | Drips, damp cabinet floors, stains |
| Listen at night | Stand in quiet rooms with nothing running | Hissing or trickling |
Seasonal and yearly checks
- January
- Dye-test every toilet and replace worn flappers.
- March
- Before irrigation season, run each sprinkler zone and walk it for broken heads and soggy areas.
- May
- Inspect supply hoses on the washer, dishwasher and fridge for bulges, cracks or corrosion at the ends.
- July
- Check the irrigation valve boxes for standing water and listen for hissing valves.
- September
- Look at the water heater: drips at fittings, rust at the base, and that seismic straps are in place.
- November
- Gently operate the main shutoff and water heater inlet so you know they still turn.
Once a year, consider asking a plumber
- Measure household water pressure and discuss whether it is too high.
- Inspect old gate valves that are stiff or do not seal.
- Look at visible supply piping in the garage, attic or under sinks for corrosion.
- Check the water heater and its connections.
- Discuss whether past leaks suggest a reroute or repipe should be planned.

Common questions
Is a monthly meter test really necessary?
It is the earliest warning you can get without tools, and it takes about ten minutes. Many people find every month or two works well.
How often should appliance supply hoses be replaced?
Inspect them yearly and replace any that are bulging, cracked or corroded. Ask a plumber or the appliance maker about their recommended interval.
Do newer homes need these checks too?
Yes. Fittings, toilets, hoses and irrigation leak in homes of any age.
